Filed: 1951-05-24
Abstract: 697,045. Machinery safety devices. AKTIEBOLAGET BOLINDER-MUNKTELL. May 24, 1951 [May 25, 1950], No. 12237/51. Class 80 (iv). A safety control device for a machine such as a press having a starting device actuated by a supply of compressed air to a plunger in a starting cylinder comprises a pair of spaced operating buttons 3, 4 requiring both hands of the operator to be employed in the starting. The buttons 3, 4 are connected through pairs of levers 5, 6 and 7, 8 to a pair of slide valves 9, 10 which control the supply of compressed air to, and exhaust from, chambers 23, 24 at the ends of an auxiliary plunger valve 21 which in turn controls the supply of compressed air to, and exhaust from, a connection 28 to the starting cylinder of the machine. The levers 5, 6 and 7, 8 co-operate with cam devices 11, 12 as fulcra so that under normal conditions button 3 operates valve 9 only and button 4 operates valve 10 only and until both of these valves are operated the auxiliary valve 21 is not moved from its left hand position shown in which the connection 28 to the starting cylinder is open to atmosphere through a port 29, the chamber 24 being supplied with compressed air from an inlet port 25 and the chamber 23 being open to atmosphere. To exhaust chamber 24 and supply pressure to chamber 23, to move plunger valve 21 to the right to supply compressed air from a port 26 to the starting cylinder, both of valves 9 and 10 must be moved from the position shown to the right against springs 14, 15, which requires simultaneous operation of buttons 3, 4. A ball-spring detent 43, 45 on the plunger 21 engages grooves 44 in its cylinder to prevent movement of the plunger unless sufficient pressure is available. Under certain conditions it may be desired to have a single button starting control and to this end the cams 11, 12 may be rotated by a coupling bar 19 to change the fulcra of levers 5, 6 and 7, 8 so that operation of either button 3 or 4 operates both valves 9, 10. The bar 19 is normally locked in a position for safety two-handed operation of the device.

SCHNEIDER & CIE, 42, Rue d'Anjou, and COMPAGNIE DES FORGES ET ACIERIES DE LA MARINE ET D'HOMECOURT, 12, Rue de la Rochefoucauld, both in Paris. April 23, 1935, No. 12257. Convention date, March 4. Addition to 404,878 and 409,215. [Class 92 (i)] Relates to means as described in the parent Specifications for hoisting and supplying ammunition to a pair of turret guns 1, 2, Fig. 2, comprising a fixed hoist 10 co - axial with the turret through which ammunition is raised into containers 14, the support 16 of which can be tilted about trunnions 23, Fig. 4, which by rotation of the trunnion support 12 can be brought parallel to the gun trunnions 3. In the prior constructions, the containers were tilted into alignment with loading trays c movable in elevation with the gun and laterally projecting from the gun cradle in a manner to restrict the elevation of the gun. According to the present invention, in order to facilitate elevation of the gun up to 90‹ the containers are spaced from the gun as shown in Fig. 2, and are swung out of the support 16 about axes parallel to themselves and subsequently tilted into alignment with the trays c by continuous operation of the same lever 29. In the construction shown in Figs. 2, 4 and 7, which relates to containers 14 for fixed ammunition as described in Specification 404,878, the lever 29 operates through rack 28 and pinion 27 to rotate bevel gearing for swinging the containers out of the support about hinges 15. The lever is connected by links 33, 32 to a locking bolt 30 engaging the disc-like trunnion 24<1> to prevent tilting of the trays until they have been swung fully outwards from the support. In the modification shown in plan in Fig. 11, which relates to the containers for separate ammunition described in Specification 409,215, four containers are simultaneously moved out of the support by a pair of racks 28 connected with the lever 29.
